Strong Choice
This formula is a protein-rich, grain-free kibble designed specifically for senior dogs of any size. It offers a relatively high protein level for older dogs, with moderate fat and added joint-support ingredients. It may suit active seniors who do well on chicken-based diets and don’t need a calorie-restricted senior food.

Where these benefits come from
Benefits the manufacturer highlights in its own product marketing. KibbleLab lists them for reference and does not verify these claims.KibbleLab Review
Strengths
- Deboned chicken and chicken meal provide concentrated, high-quality animal protein as the main ingredients.
- The 34% protein with moderate fat can work well for many healthy, active senior dogs.
- Added glucosamine and chondroitin can help support joint health in aging dogs.
- Omega-3 and omega-6 fatty acids plus fruits and vegetables offer additional skin, coat, and antioxidant support.
Considerations
- Chicken, turkey, and egg are common allergens, so this food is not ideal for dogs with sensitivities to those proteins.
- As a grain-free food relying on peas and potatoes, it may not be the best choice for breeds with known heart concerns without veterinary guidance.
- The calorie density is fairly high for a senior diet, so careful portion control is important for dogs prone to weight gain.

Top 5 Ingredients Explained
01
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.

03
Turkey
Turkey is commonly used as a primary animal protein in dog and cat foods, offering highly digestible, high‑quality protein and supplying essential amino acids along with B vitamins, phosphorus and zinc to support muscle maintenance and metabolism. Its fat level varies by cut so products can be lean or richer; some pets may develop allergies to poultry, cooked bones are hazardous, raw meat carries bacterial risk, and owners should rely on balanced commercial formulations (and ensure adequate taurine for cats) if turkey is a main ingredient.

04
Potato
Potato is commonly used in pet foods as a digestible carbohydrate source and functional binder, supplying starch, fiber, and modest amounts of vitamins (B6, C) and potassium—often included as cooked or dehydrated flakes, starch, or protein concentrates. While it provides energy and helps formulate grain‑free recipes, potatoes are not a primary protein for dogs or cats (and are not nutritionally required for obligate‑carnivore cats), can contribute to excess calories or affect blood glucose in diabetic animals, and must be cooked and free of green skins or sprouts to avoid solanine toxicity; allergies are uncommon but possible.

05
Pea
Pea is a plant-based ingredient used in pet foods as a source of protein, soluble and insoluble fiber, and micronutrients (often included as whole peas, pea flour, or pea protein concentrate) to boost protein content and improve texture. While peas can provide digestible carbohydrates, fiber, and some plant protein useful especially for dogs, they are not a complete protein for obligate carnivores like cats and — when overused, particularly in concentrated forms or as a major component of grain‑free diets — have been scrutinized for a possible association with canine dilated cardiomyopathy and can contribute to nutrient imbalances or excess calories, so balanced formulation and compliance with AAFCO nutritional profiles are important.
